TRANSPARENT MAKE-UP PLATE FOR USE IN PRODUCING PAGE STEREOTYPE.

Application filed June 30, 1926, Serial No. 119,762. Renewed February 9,1928 I am the inventor of those novel processes for printing stereotypesdisclosed and claimed in my two applications for U. S. Letters Patentthereon, filed June 10th, 1926, under Serial Numbers 115,129 and115,130.

I am also the inventor of that novel process for producing page printingstereotypes disclosed in that certain application for U. S. LettersPatent thereon, executed by me of even date herewith, filedcontemporaneously with my present application and numbered 119,7 61.

In the second and third steps of the processes disclosed in my lastabove referred to application, I employ what is there called atransparent make-up plate, to which all the master sheets desired for asingle page of printed matter are secured and thereafter handled, in theproduction of the page stereotype.

I am the inventor of said transparent make-up page plate and the same isthe subject of this present application.

Two forms of such a transparent make-up page plate are illustrated inthe accompanying drawings.

In said drawings like notations refer to like parts throughout theseveral views.

Fig. 1 is a plan view of an integral transparent make-up plate, of thekind which would be generally employed, shown on a scale of about onethird size;

Fi 2 is a vertical section through a portion of said integral plate onthe line 2-2 of Fig. 1, on a much larger scale than in Fig. 1, beingfull size;

Fig. 3 is a horizontal section through a portion of said integral plateshown in Fig. 1 on the line 33 thereof shown full size;

Fig. 4 is a plan view of a sectional transarent make-up plate, with thesections iield properly joined together in a printers chase, on a scaleof about one third full size;

Fig. 5 is a vertical section through portions of the parts shown in Fig.4 on other parts being broken away, size; an

Fig. 6 is a horizontal section through some of the parts shown in Fig. 4on the line 6-6, other parts being broken away.

Referring now, in detaii, to the parts shown shown in full the line 5 5.

in Figs. 1, 2 and 3, the numeral 7 denotes the integral transparentmake-up plate, which is preferably composed of a good quality of glass.This plate 7 is of sufficient size to hold all the master sheets ofcomposition required or desired for a page of a newspaper or otherpublication. This plate 7 is provided on its face with a series ofproperly spaced column demarking grooves 8 countersunk therein parallelwith each other and extending from near the top to the bottom of theplate, as clearly shown in Figs. 1 and 3, and is also provided with aseries of paragraph demarking grooves 9, countersunk therein disposedparallel with each other and running crosswise of the plate at rightangles to the column demarking grooves 8. Of the column demarkinggrooves 8, there will be as many, on the face of the plate, as therewill be columns in the page of the newspaper or other publicationintended to be printed. Of the paragraph demarking grooves 9, there willbe enough, on the face of the plate. to provide for the demarking ordistinguishing of all the paragraphs of composition intended to appearon the printed sheet. In other words, the face of the said plate 7 willcontain many more of the paragraph demarking grooves 9 than would likelybe used for any single page of composition. The purpose of this excessnumber of said grooves 9 is to afford selective locations to fit theparagraphs of the composition of the master sheet for any given page ofprinted matter.

In the modification illustrated in Figs. 4, 5 and 6 of the drawings, aseries of glass sections 10 are employed to constitute the transparentmake-up page plate of the proper size, with these sections 10 properlyabutted and held together in a suitable chase 11. The chase 11 is oflarger size than the make-up plate composed of the glass sections 10,and the clamping action is secured by set screws 12 seated in the chaseframe and hearing at their inner ends against pieces of printersfurniture 13 working as abutments against the corresponding adjacentedges of the sectional make-up plate, as clearly shown in Fig. 4 of thedrawings. These pieces of furniture 13 are preferably composed of wood,so that they will yield slightly under the action of the set screws 12,thereby securing reliable clamping of the sectional make-up plate to thechase frame.

This sectional make-up plate shown in Figs. 4, 5 and 6 is provided onits face with column demarking grooves 8 and paragraph demarking grooves9 similar to the corresponding grooves of the integral plate shown inFigs. 1, 2 and 3.

Respecting the chase frame 11, it should perhaps be noted that its sideand end mem bers are rabbeted on their inner opposing faces to affordinwardly projecting flanges 11, best shown in Fig. 6, upon which theframe adjacent members of the glass sections 10 of the make-up plate mayrest, when properly positioned within the chase. It should also be notedthat the vertical depth of the rabbeted channels alfording the flanges11 is less than the thickness of the glass sections 10, so that when theglass sections 10 are properly positioned in the chase, the face of themakeup plate will be a little higher than the frame members of thechase, as clearly shown in Fig. 6 of the drawings.

The word composition as herein used, and as used in my otherapplications above referred to, is employed in a broad sense to coverand include not only reading matter, but impressions made from cuts, orfrom half tones, or from electroplates, for use in association with thereading matter or independently of the reading matter.

he expression master sheet or master sheets as herein used, is employedin the same sense as in my other cases hercinbefore referred to. In oneform thereof the body of the master sheet is translucent and thecomposition thereon is in opaque impressions. In another form thereofthe body of the master sheet is opaque and the composition therein is intranslucent impressions. The first named form can be prepared on atypewriting machine, by using a good quality of white paper, with acarbon faced to the back of the paper, thereby getting impressions bothon the face and on the back of the white sheet, and these will besufficiently opaque to prevent rays of light from passing therethrough.The other form of master sheet can also be prepared on a typewriter byusing a wax faced thin sheet of fabric of the kind ordinarily used formimeographing. The Hammond machine is best adapted for this purpose, asthe impressions are secured on that machine by blows against the sheetwhen held stationary against the face of the type. lVhen so treated, thewax on the face of the sheet will be displaced at the surfaces thereofstruck by the tyneor more accurately speaking-bearing against the faceof the sheet at the time the blow occurs, thus rendermg the impressionson said opaque sheet translucent. The master sheets for what isordinarly called out matter to wit: matter printed from cuts, halftones, or electroplates is obtained from such cuts, half tones orelectroplates in the ordinary way and then used in association with thereading matter master sheets.

lVith the foregoing explanation in mind, the usage and advantage of mytransparent make-up page plate herein disclosed can readily beunderstood.

Assuming that all the master sheets of composition, whether for readingmatter alone, cut matter alone, or the two kinds of composition inassociation with each other, have been prepared for a single age ofprint, they will be assembled in the order desired on the face of thetransparent make-up plate, and will be pasted fast thereto, andthereafter be handled therewith. The presence of the column demarkinggrooves and the paragraph demarking grooves on the face of said make-upplate, facilitates the assembling of said master sheets and the accuracyof their location thereon. If it is desired that the columns and theparagraphs on the printed page shall only be distinguished by whitespaces, then no inking of the said grooves of the make-up plate isnecessary; but of it is desired to distinguish or demark the columns ofprint by black lines or the paragraphs of the columns from each other byblack lines, then the said column and para graph grooves of the faceplate are filled with ink by a ruling pen before the master sheets areassembled on and pasted fast to the face of said plate. The filling ofsaid grooves with ink makes the faces of the filled grooves opaque, sothat the rays of light cannot pass therethrough.

After the master sheets have been secured to the said transparentmake-up plate, they are handled collectively with said plate in securinga transfer of the composition to the face of a metallic stereotypingplate, in the same way as described for unmounted master sheets in mypending applications, S. N. 115,129 and s. N. 115,130. In other words, asuitable zinc or copper stereotyping plate is provided havin its facesensitized with a material which is normally soluble in water but can bemade insoluble in water by exposure to light. The said make-up sheetcontaining said assembled master sheets is then applied face downward tothe sensitized face of said stereotyping plate and subjected to a stronglight, such as an electric are light. The result will be that thesensitized material on the surfaces of said stereotyping plate notcovered by the opaque composition impressions of the master sheet willbe rendered insoluble in water by the actions of the rays of lightthereon. The rays of light, however, cannot pass through the portions ofthe master s eets occupied by the opaque c0mposition impressions orthrough the grooves of said make-up plate occupied by ink, and

- grooves in the face of the make-up hence, the sensitized material onthe surfaces of the stereotyping plate covered by said 0 aquecomposition impressions of the master s eets covered by the opaque inkfilling of the plate will remain insoluble in water. Then thestereotyping plate is washed with water, to

. remove the sensitizing material from the surfaces thereof which hadbeen covered by the o aque impressions of the master sheets and t e inkfilled grooves of the make-up plate,

thereby leaving all the printing sur es exposed. Then said exposedsurfaces of said stereotyping late are covered with a material whichWlll resist the chemicals used in the next two steps. Ordinary printersink will serve this purpose, and can be readily applied with suitableinking roller. Then the sensitized material is removed from the surfacesof said plate which have not been covered by the opaque im ressions ofthe master sheet, and the ink filled grooves of the make-u plate, whichcan readily be done by swab ing the stereotyping plate with a dilutesolution of hydrochloric acid. Then the next or final step consists inetching off from the face of said metallic stereotyping plate all theface surfaces thereof not corresponding to the composition of the mastersheets and the column and paragraphing demarkin lines of the make-upsheet.

The a1 result is a page stereotype in flat form, which could be used onsome forms of printing presses. For newspaper work, how ever, the at agestereotype would be curved, to half cylin er form, by the suitableapplication of pressure thereto, and these curved stereotypes of halfcylinder form would be mated 1n-the proper sequence, and ap lied to thecylinders of the printin press in t e same way as curved stereotypes rommatrix molds are now applied.

In the foregoing description of the making of the page stereotype, ithas been assumed that the preferred form of m process dis- CluSGCl in myfoundation app ication S. N. 115,129 will be employed. If the modifiedform therein disclosed and broadly claimed and also disclosed andspecifically claimed in my a plication S. N. 115,130 is used, corresponing changes in the description of the steps to be followed for producinga page stereotype would have to be made. In the foregoing description,my transparent makeup pa e plate no attention has been called to thetitle of the page. If that title happens to be a permanent one, like inthe case of newspapers no special aper master sheet thereof is needed,but, on t e contrary, said title ma be painted directl on the glassplate in blac paint or ink and t en will act in the same way as themaster sheets of composition.

The integral form of the transparent make-up plate would generally beemployed for master sheets containing the ordinary reading mattercomposition. The sectional form of the transparent make-up plate could,and robably would, be employed or the master s eets containin displayadvertisements; for the reason t at it would enable proofs of individualads to be furnished to the different advertisers from the master sheetsof such advertisements (by blue printing the same from the mastersheets) in advance of the general assembly thereof on the make-up pa eplate, and then, if the advertisers shoul make corrections or changes,after seeing said proofs, it would only be necessary to correct themaster sheets of the particular advertisements corrected. It is also anadvantage for shifting or varying the relative positions of thedifferent advertisements of different advertisers. Each glass section ofthe said make-up plate may be devoted to a particular advertiser; andthen, the glass sections could be shifted relative to each other asdesired, in the make-up or assembly thereof in the chase, so as therebyto give any desired relative positions to the different advertisementsof the different advertisers.

Said glass sections 10 of the sectional make-up plate are, whenassembled, joined together on lines which coincide with the columndemarking lines 8 and the aragraph demarking lines 9 thereof. In 0t erwords, the vertical joints of said lass sections will coincide with thecolumn demarking lines 8 and horizontal joints of said sections willcoincide with paragraph demarking lines 9. On Fig. 4 of the drawingsthese jointure lines of the sections are shown heavier than the othercolumn demarking or paragraph demarking lines, in order to make theboundar lines of the glass sections 10, when assemble more distinct tothe eye. For the same reason said glass sections 10, as shown on saiddrawing, are so shaded as to help distinguish the several sections fromeach other, to the eye. In practice, however, it will be understood,that the jointure lines of said glass sections 10, when assembled, inthe chase, would be of the same size as the column demarking or paragrah demarking lines with which the coincid e.

t should, perhaps also be noted that, in practice there would be a largenumber of said glass sections 10 of different sizes, available fromwhich selections could be made for the particular make-up of any desiredpage, whether the age is to be wholly of ads or partially of ass andpartially of reading matter composition.

It may also be further noted that the particular mar 'nal glass sections10 which are to be place with their outer edges directly abutting thecorresponding chase frame members, on the sides of the chase opposite tothe clamping members of the chase, will be a little larger in one or twodimensions, in

order to afiord marginal portions adapted to overlie and rest upon theinwardly pro ecting marginal flanges 11 of said chase frame membersagainst which said glass sections abut, as clearl shown in F1 4 and 6.These marginal portions of said particular glass sections 10 will not beoccupied by any of the master sheets of composition, for the obviousreason that the rays of light must come from the back when the make-upplate is applied to the metallic stereoptyping plate, for getting thetransfer of the composition, and of course said rays of light can onlypass through the exposed part of the glass.

What is claimed is:

1. A transparent make-up page plate, having parallel column demarkinggrooves and parallel paragraph drmarking grooves at right angles to saidcolumn demarking grooves, for assembling thereon and handiing togetherall the master sheets of composition required for a printed page, inproducin a a e stereot of said composition, su staiitia lly as desbz ibed.

2. A transparent make-up page plate, composed of sections of glassabutting each other adapted to support on their faces takencollectively, all the master sheets oi composition required for aprinted page, for handling the same together in producing a pagestereotype of said corn osition.

3. The combination wit a chase and clamping devices of a transparentmake-up page plate composed of sections of glass adapted to be heldabutted edgewise together in said chase by said clamping devices, andwhich glass sections, taken collectively, are adapted to hold on theirfaces all the master sheets of composition r uired for a printed page,for handling sai master sheets together in producing a page stereotypeof said composition.

In testimony whereof I ailix my signature.
